MEAT-CUTTING- MACHINE.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed October 4, 1905. Serial No. 281,353.

To all whom it may concern:

Be it known that I, LEO Anscnnn-a subject of the German Emperor,residing at Dortmund, in the Province of Westphalia and Kingdom ofPrussia, have invented certain new and useful Improvements in Meat-Outting Machines, of which the following is a specification.

My invention relates to meat cutting machines of the type in whichrotating circular knives or cutters are employed to successively cutthin slices from a piece of meat, which is held in a frame or the like.

The object of my invention is to provide an improved meat cuttingmachine having a rotating circular cutter, in which the forward movementof the cutter, during the cutting operation, is slower than the backwardmovement away from the meat, and in which the cutting plane of thecutter, during its advance movement, is continuously changed, so thatthe cutting face of the cutter is always at an angle with respect to theplane of the cut. The continuous change of the position of the cutterwith respect to the cut is accomplished by moving the cutter in an arcwhose radius is at an angle, and preferably at a right angle, to theplane of the cut. The slow forward and quick backward movement iseffected by the operation of a crank-disk, whose axis is so situatedthat the point of connection between the connecting bar attached to thesaid crank-disk and the cutter moves in an arc, which is located at aconsiderable distance above the axis of rotation of said crankdisk.

On the accompanying drawings Figures 1 and 2 show in top view and sideelevation respectively the new machine. Fig. 3 shows the different formsof cutters in the operation of cutting.

Similar reference characters designate similar parts in all the figures.

Referring to Figs. 1 and 2, the rotary cutter a is movably mounted toswing back and forth, towards and away from the piece of meat t, whichis firmly clamped in a frame r adapted to reciprocate in guides q, andso arranged that during the cutting the meat can be fed successivelyforward.

The operation of the various parts is effected from a hand wheel 12,which, when rotated, operates by means of a pinion s a crank-disk itprovided at its under side with teeth engaging the pinion s. 'A rod d,fastened to said crank-disk it, has its other end pivotally connectedwith a frame 6, adapted to swing around a pivot f and carrying at itsouter end the rotary cutter a, the arrangement being such that, if thecrank-disk u is rotated around its axis by turning the hand-wheel b, thecutter frame e is, by means of the connecting rod d, swung back andforth in an arc. Fastened to the crank-disk u, or made integraltherewith, there is provided a sprocket-wheel c, which is rotatedtogether with the crank-disk u, and rotates, by means of chain '0(Fig. 1) a similar sprocket-wheel 9, having its axis of rotationcoincident with the fulcrum f of the cutter frame e. The sprocket-wheelg imparts its own rotary movement by means of a shaft wand gearing to ashaft h, both shown in Fig. l in dotted lines, the shaft h beingrotatably journaled in frame a. At the forward end of shaft h is mountedthereon a sprocket-wheel y driving through a chain 3' a sprocket-wheel zand thus rotating the circular cutter a, secured on 'the axis of saidsprocketwheel 2 the said axis being mounted in a bracket 6 of frame e.Each time, the cutter a is swung backward, the frame 1" holding thepiece of meat is fed forward by means of a screw-spindle 1', shown inFig. l, the spindle being turned by hand by means of a small thumb screw2".

In Fig. 3 two different cutters are shown, to illustrate the cuttingoperation, the cutter a shown in the upper figure being a hollow groundcutter and the cutter shown in the lower figure being a straight diskcutter. In each case, the cutting edge occupies the position of atangent with relation to the periphery of a circle, the out beingeffected therefore in the shape of an arc, the cutting edge at all timesduring the cutting operation occupying the same angular position withrespect to the cut face of the meat.

What I claim is A meat slicing machine comprising a reciprocating frameadapted to hold the meat, a frame pivoted so as to swing back and forthin an arc towards, and away from, the said reciprocating frame, asprocket wheel rotatably mounted in said swinging frame, a circularcutter mounted on the axis of said sprocket wheel, a crank disk, a rodsecured thereto and pivotally connected to said swinging frame, meansbetween said crank disk and said sprocket wheel to impart the rotationof the former to the latter thereby rotating the rotary cutter, andmeans to successively feed forward the reciprocating frame holding themeat.

In testimony whereof I aflixed my signature in presence
